A system administrator is decommissioning a server and needs to migrate an LVM volume group named vg_san to a new machine. The volume group resides on shared SAN LUNs. Before the LUNs are reassigned to the new server, what is the final command the administrator must run on the original server to mark the volume group as available for import on another host?
The correct command is vgexport vg_san. The vgexport command makes an inactive volume group unknown to the local system, which is the necessary step before its physical volumes (in this case, the SAN LUNs) can be moved to another system for import. The vgremove command would permanently delete the volume group and its associated logical volumes, resulting in data loss. The vgchange -an vg_san command deactivates the volume group, which is a required prerequisite, but it does not export it. The vgimport vg_san command is used on the new system to make the exported volume group available after the storage has been moved.
